Export annotated dataset feature not working as expected

I am having trouble in exporting the annotated dataset, when trying Segmentation Mask 1.1 format. I keep getting only 3 items in the zip - labelmap.txt, JPEGImages, ImageSets. I dont see SegmentationClass or SegmentationObject items in the zip at all, despite my having labeled a few objects in the images. This is a consistent behaviour. Anything I might be missing?

Expected Behaviour

The exported zip should contain the 5 items - labelmap.txt, JPEGImages, ImageSets, SegmentationClass and SegmentationObject

Current Behaviour

I keep getting only 3 items in the zip - labelmap.txt, JPEGImages, ImageSets.

Steps to Reproduce (for bugs)

1. Create a new labeling job by uploading a sequence of images.
2. Draw polyline around the objects in the image. (Shape, not Track)
3. Save
4. Export Task dataset > Format : Segmentation Mask 1.1 (Include images or not) > enter zip name > OK

Context

I am not able to export the labeled dataset, and do not know where to look for logs for this process specifically. docker logs doesnt give any helpful logs unfortunately.

Draw polyline

A polyline is infinitely thin. It will not be drawn on a segmentation mask. Use polygons instead.

@sebkken, could you describe what is the expected result? Currently, we only export 2d annotations with non-zero area, i.e. boxes, polygons and ovals (docs).

@bsekachev @zhiltsov-max Thanks for the information. We started using the polygons instead of polylines, and this issue has been resolved. Thanks so much for the prompt response.
